We had 8 nights at Hotel San Pietro.
Location: Central - close to the central railway-station.
Surroundings: Napoli at its worst - ugly, ugly and UNSAFE!
Room: Had booked and paid for a junior suite with only one small window towards a dark backyard - could not see whether it was day or night. Ended in an ordinary room with more light - however no apologies, no compensation - no nothing. Not even a bottle of wine - or at least a bottle of WATER.
Breakfast: Apart from a little bit of fresh fruit, mainly sweet cakes.
Wifi: Very, very weak, almost not existing, could not be used for anything, could not check in on the phone when homebound - a huge problem as the 4G network in Naples is poor too.
Hygiene factors: Yes, the hotel was clean. Yes the staff was kind.
Conclusion: Next time in Naples - ANOTHER HOTEL.
